- Flexible thermoplastic polyurethane (TPU)
- High abrasion resistance and chemical resistance
- Excellent layer adhesion for 3D printing
- Low shrinkage and UV resistant
- Suitable for a range of applications including medical devices, automotive parts, and mobile phone cases
The TPU filament from SainSmart is a versatile and multiuse material that stands out for its rubbery elasticity and durability. Unlike TPE filament, which it is often compared to, TPU boasts a higher level of abrasion resistance, chemical resistance, and significantly lower shrinkage, making it ideal for precise measurements post printing. It shines in industrial uses with its resistance to grease, oil, and solvents, making it particularly valuable for producing parts for medical devices, automotive instrument panels, power tools, and even everyday items like phone cases and footwear. Designed to achieve excellent layer adhesion, TPU allows creators to print with variable flexibility by adjusting the infill settings - less infill means a more flexible finish. UV resistance and the retention of elastic properties at lower temperatures ensure that TPU is also the filament of choice for outdoor applications or mechanical parts, and its compatibility with dual extrusion printers enables mixing with rigid base materials for composite structures.
